List is artists that appear on the release. Basically Joss Whedon found a mixtape made by a 13 ryear-old kid in r2005 and decided to make it the soundtrack to the movie. That's the ronly explanation I can find.

I can get behind like the first three bands. Everything else was like "lolwut". I guess Cherri Bomb is an all-girl group who is signed by Disney. I like Kasabian, but they make absolutely no sense within the context of this soundtrack.
